Load binder of the single flow lever type



Feb. 8, 1966 H. s1. PIERRE LOAD BINDER OF THE SINGLE FLOW LEVER TYPE Filed April 15, 1964 INVENTOR. #51. T 35m! United States Patent 3,233,369 MEAD BINDER @F THE SINGLE FLUW LEVER TYB E Henry St. Pierre, 54) Frank t., Worcester, Mass. Filed Apr. 15, 1964, Ser. No. 36%,iiil3 3 Claims. (Q1. 254-75) This invention relates to new and improved load binder, and the principal object of the invention resides in the provision of improved lever action for load binders so that additional pull may be imparted to a chain or cable being tightened; the provision of a new and improved load binder which is easier to operate than those of the prior art; the provision of a novel load binder including a lever pivotally mounted with relation to a clevis, said lever being provided with a pivoted hook at one end and a cooperating pivoted hook at a point inwardly from said end with the engaging device for the chain located between these pivot points, providing for increased ease of operation as well as ease of application of the device to the chain to be tightened, and including improved result of providing for an application of increased stress to the chain or cable being tightened.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing, in which FIG. 1 is a view in elevation showing the new load binder applied in loose condition to a chain to be tightened, parts being broken away;

FIG. 2 is a view similar to FIG. 1 but showing the chain in tightened condition;

FIG. 3 is a perspective view illustrating the bifurcated nature of the lever; and

FIG. 4 is a perspective view illustrating the relationship of the bifurcated lever with respect to the device.

As shown in FIGS. 1 and 2, a length of chain is indicated as having an end link it and this chain is to be tightened around the load or in some similar relationship With respect to a chain that is generally indicated at 12.

The load binder itself comprises a hook l4 pivotally mounted as by an eye 16 and connecting link 18 with a swivel 20, said swivel being mounted on the closed end of a clevis 22, the latter of course having two spaced arms as clearly shown in FIGS. 3 and 4.

The open ends of the arms of the clevis include between them the extreme end of a lever generally indicated at 24. The section of the lever 24 that is included between the arms of the clevis is bifurcated providing a pair of arms 26 pivoted as at 28 with respect to the c;evis.

Adjacent the junction of the bifurcated lever arms 25 with respect to the main portion of the lever 24 the arms 26 are pivotally secured as at 3h to a link 32 terminating in a swivel 34 having an eye 36 connected to a link 38 pivotally mounting another hook 43.

At a point located between the pivots 23 and 30, there is provided a link-engaging lip or shoulder 4-2, there being one of these lips or shoulders 42 on each lever arm 26 as clearly shown in FIG. 4, and it is to be particularly observed that the shoulders or lips 42 are located between the pivot points 28 and 30, regardless of the relative position of the lever 24 with respect to clevis 22. Each lip 42 is straight-edged and not hooked, as this is unnecessary with the lips positioned in the novel manner shown.

In the operation of the device, hook 14 is engaged with the end link as shown in FIG. 1, and the other hook 40 is engaged with a convenient link forming part of chain 12. The hooks may be engaged in the link or about the link, so that the load binder may be relatively tightly connected to the two ends of chain as shown in FIG. 1.

A link 44 of chain 12 is located so as to engage the lips or shoulders 42 at either side of a side run of an adjacent link 46, see FIG. 1. The handle of lever 44 is then moved in the appropriate direction to draw the chain 12 downwardly with respect to the chain of W1 ich 143 is a part and this causes the link 46 to enter the space between the bifurcated lever arms 26 as clearly shown in FIG. 2, link 44 and the adjacent links also being drawn through in order to stretch the chain or to make the same tight relative to the load which is being held.

With the parts as shown in FIG. 2, the hook 40 is released from its link and may now easily be raised a link or several links further up along the length of the chain 12 and then when the lever 24 is released so as to proceed again in the opposite direction, the two hooks 14 and It) will hold the chain in its tightened condition. This operation may of course be repeated as long as it is desired to further tighten the load.

The device may be used upside-down also, so that when the chain is being stressed, the operator may push downwardly on lever 24 rather than upwardly.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

1. A load binder comprising a lever having a bifurcated end, a clevis pivotally embracing the lever adjacent the end of the bifurcated portion thereof, a hook, means swivelly securing the hook to the clevis, a second hook swivelly attached to the lever at a point remote from the first hook, and a link engaging shoulder on each arm of the bifurcated portion of the lever, said shoulders being located between the pivot points of the two hooks and closely adjacent the pivot point between the lever and clevis.

2. A load binder comprising a lever having a bifurcated end, a clevis pivotally embracing the lever adjacent the end of the bifurcated portion thereof, the lever and clevis being interpivoted adjacent the open ends thereof, a hook swiveled to the clevis at the closed end thereof, a second hook swiveled to the lever at a point remote from the junction of the clevis and lever, and chain link engaging devices on the bifurcated portion of the lever, said devices being located intermediate the junction of lever and clevis and the pivot axis of the second hook and the lever.

3. A load binder comprising a lever having a bifurcated end, a clevis pivotally embracing the lever adjacent the end of the bifurcated portion thereof, the lever and clevis being interpivoted adjacent the open ends thereof, a hook swiveled to the clevis at the closed end thereof, a second hook swiveled to the lever at a point remote from the junction of the clevis and lever, and chain link engaging devices on the bifurcated portion of the lever, said devices being located intermediate the junction of lever and clevis and the pivot axis of the second hook and the lever, said chain link engaging devices each comprising an integral lip extending laterally from the respective part of the bifurcated lever.
